The DfsInserter writes the pack and its indices in the flush() method,
but when the writing happens via DfsPackParser, it is the parser which
writes the pack and indices. When combined with a parser, flushing the
inserter is a noop.
Add the writing of the object size index to the packparser#parse
method, mirroring how the primary index is written.

PackWriter knows how to add an object size index to the pack, but the
garbage collector is not using it yet.
Teach DfsGarbageCollector to write the object size index on
writePack(). Disable by default in the unreachable-garbage pack.
Callers control the content/presence of the index through the
PackConfig option (minBytesForObjSizeIndex) for all other packs, so
there is no need of a specific flag in DfsGarbageCollector.

isNotLargerThan() can avoid reading the size of a blob from disk using
the object size idx if available.
Load the object size index in the DfsPackfile following the same

Following CL introduces the writing of the object size index and the

The packfiles with the .keep extensions are meant to prevent
a packfile from being processed or removed during GC.
From the point of view of the GC process then, the associated
packfile should be completely transparent:
- it should not included in the repacked file
- it should not pruned
- its objects should be left untouched, even if unreachable
- the GC process, including the bitmap generation should continue
as usual, as the the packfiles with .keep file did not exist
Add one explicit test for making sure that the management
of .keep file is also transparent to the generation of bitmaps,
which are still generated if a .keep file exists.

Add an explicit flag to PackWriter for allowing the
GC.repack() phase to explicitly generate bitmaps only for the
heads packfile and not for the others.
Previously the bitmap generation was conditioned to the
presence of object ids exclusion from the PackWriter.
The introduction of the bitmap generation in the PackWriter
done in Icdb0cdd66 has accidentally made the .keep files not
completely transparent, because their presence have disabled
the generation of the bitmap index, even if the generation
of bitmaps is enabled.
This bug has been an accidental consequence of the intention
of the bitmap generator to avoid generating bitmaps for the
non-heads packfile, however the implementation done by Colby
decided to use the excludeInPacks variable (see [1]) which
is unfortunately also used for excluding the packfiles having
an associated .keep file (see [2]).

When loosening the objects inside the packfiles to be pruned, make sure
that the packfile list is stable and prune all the files after the
loosening is done.
This prevents a series of exceptions previously thrown when loosening
the packfiles, due to the too early pruning of the packfiles that were
still in the pack list.

Update `getSize` method in `S3Repository` to handle larger object sizes.
The method previously used `Integer.parseInt`
to parse the `Content-Length` header of an HTTP response,
which limited the maximum object size to 2 GB.
Replaces `Integer.parseInt` with `Long.parseLong`,
allowing the method to handle object sizes larger than 2 GB.
- Use minio as local S3 service for gerrit lfs plugin
- The minio seems will return the Content-length

The DfsPackFile#getReverseIdx method, which wraps creating a
PackReverseIndex in caching, was package-private. This caused
implementations on top of DfsPackFile to directly instantiate a
PackReverseIndex in cases where it would benefit from caching.
Instead, make #getReverseIdx public so that the caching logic can be
reused by implementations where appropriate.

PackReverseIndex is a concrete class whose implementation is computed
from a pack's forward index. Callers which have a reverse index file may
want to use an implementation that is file-based instead.
Generalize PackReverseIndex into an interface without
implementation-specific logic and separate out the logic for the
computed implementation into a new concrete class.

C git has a default for git config core.excludesfile: "Its default
value is $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either
not set or empty, $HOME/.config/git/ignore is used instead." [1]
Implement this in the WorkingTreeIterator$RootIgnoreNode.
To make this testable, mock the "user.home" directory for all JGit
tests, otherwise tests might pick up a real user's git ignore file.
Also ensure that JGit code always reads "user.home" via the
SystemReader.
Add tests for both locations.

This fixes all the javadoc warnings, stops ignoring doclint 'missing'
category and fails the build on javadoc warnings for public and
protected classes and class members.
Since javadoc doesn't allow access specifiers when specifying doclint
configuration we cannot set `-Xdoclint:all,-missing/private`
hence there is no simple way to skip private elements from doclint.
Therefore we check javadoc using the Eclipse Java compiler
(which is used by default) and javadoc configuration in
`.settings/org.eclipse.jdt.core.prefs` files.
This allows more fine grained configuration.
We can reconsider this when javadoc starts supporting access specifiers
in the doclint configuration.
Below are detailled explanations for most modifications.
@inheritDoc
===========
doclint complains about explicits `{@inheritDoc}` when the parent does
not have any documentation. As far as I can tell, javadoc defaults to
inherit comments and should only be used when one wants to append extra
documentation from the parent. Given the parent has no documentation,
remove those usages which doclint complains about.
In some case I have moved up the documentation from the concrete class
up to the abstract class.
Remove `{@inheritDoc}` on overriden methods which don't add additional
documentation since javadoc defaults to inherit javadoc of overridden
methods.
@value to @link
===============
In PackConfig, DEFAULT_SEARCH_FOR_REUSE_TIMEOUT and similar are forged
from Integer.MAX_VALUE and are thus not considered constants (I guess
cause the value would depends on the platform). Replace it with a link
to `Integer.MAX_VALUE`.
In `StringUtils.toBoolean`, @value was used to refer to the
`stringValue` parameter. I have replaced it with `{@code stringValue}`.
{@link <url>} to <a>
====================
@link does not support being given an external URL. Replaces them with
HTML `<a>`.
@since: being invalid
=====================
org.eclipse.jgit/src/org/eclipse/jgit/util/Equality.java has an invalid
tag `@since: ` due to the extra `:`. Javadoc does not complain about it
with version 11.0.18+10 but does with 11.0.19.7. It is invalid
regardless.
invalid HTML syntax
===================
- javadoc doesn't allow <br/>, <p/> and </p> anymore, use <br> and <p>
instead
- replace <tt>code</tt> by {@code code}
- <table> tags don't allow summary attribute, specify caption as
<caption>caption</caption> to fix this
doclint visibility issue
========================
In the private abstract classes `BaseDirCacheEditor` and
`BasePackConnection` links to other methods in the abstract class are
inherited in the public subclasses but doclint gets confused and
considers them unreachable. The HTML documentation for the sub classes
shows the relative links in the sub classes, so it is all correct. It
must be a bug somewhere in javadoc.
Mute those warnings with: @SuppressWarnings("doclint:missing")
Misc
====
Replace `<` and `>` with HTML encoded entities (`< and `>`).
In `SshConstants` I went enclosing a serie of -> arrows in @literal.
Additional tags
===============
Configure maven-javad0c-plugin to allow the following additional tags
defined in https://openjdk.org/jeps/8068562:
- apiNote
- implSpec
- implNote
Missing javadoc
===============
Add missing @params and descriptions

In org.eclipse.jgit.lib.Constants the constants are all marked final
with the exception of:
- COMMIT_GENERATION_UNKOWN
- COMMIT_GENERATION_NOT_COMPUTED
They were introduced by cf70e7cbe4 without the `final` keyword while
other constants have it which certainly has been forgotten.
The javadoc `{@value}` tag causes raises a warning about the fields not
being constants which is how I have discovered the ommission.

This reverts commit 9c33f7364d.
Reason for revert: This change was based on the false claim that the
packedrefs file lock is held while the CAS is being done, but it is
actually released before the CAS (the in memory lock is still held,
however that does not prevent external actors from updating the
packedrefs files and then another thread from subsequently re-reading it
and updating the in memory packedRefList). Although reverting this
change can cause the CAS to fail, it should not actually matter since
the failure would indicate that another thread has already updated the
in memory packedRefList to either the same version this thread was
trying to update it too, or to a more recent version. Either way,
failing the CAS is then appropriate and should not be problematic.
Although this change reverts the code in the RefDirectory class, it
keeps the "improvements" to the test so that it continues to pass
reliably. The reason for the quotes around the word "improvements" is
because I believe the test alteration actually dramatically changes the
intent of the test, and that the original intent of the test is
untestable with the GC and RefDirectory classes as is.

(cherry picked from commit c5617711a1)
PackReverseIndex instances are created using the constructor directly,
which limits control over the construction logic and refactoring
opportunities for the class itself. These will be needed for a
file-based implementation of the reverse index.
Use a static builder method to create a PackReverseIndex instance using
a pack's forward index.

Make garbage collection write the reverse index file when the PackConfig
enables it. Write it during #writePack, which mirrors how the primary
